ADJUSTABLE HANDLE-SOGKET.

Application filed. November 3, 1919.

To all whom it may concern:

Be it known that 1, PETER J. Moron, a citizen of the United States, and a resident of the city and county of San Francisco, State of California, have made a new and useful Invention, to wit, Adjustable Handie-Sockets; and I do hereby declare the following to be a full, clear, concise, and exact description of the same.

This invention relates particularly to an adjustable socket for joining a handle to a brush, mop, tool or the like.

The wooden backs of brushes, mops, brooms and the like under standard manufacturing conditions are generally pro vided with threaded holes, bored on a' slant, to receive the threaded end of the handle. In time the constant screwing and unscrewing of the handle, strips the threads on both the handle and in the wooden back thus shortening the usefulness of the brush or broom. It is an object of my improvement to require but one threaded hole in the back of the brush or broom and to secure my invention therein, and by the construction hereinafter described to obtain any adjustment of handle position desired, eliminating the necessity of boring slanted holes in the brush back land of threading the end ofthe handle.

Another object of this invention is to provide a simple and efiicient handle socket possessing durable, and rugged qualities and small and compact in size so that its weight will be negligible when it has been applied to a brush or broom. A further object is to so construct and constitute the same that the handle may be adjusted to any position, in the same plane, in an arc of substantially one hundred and eighty degrees, while the operator maintains his normal working position.

In this specification and the annexed drawing, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms, and it is also to be understood that in and by the claims following the description it is desired to cover the invention in whatsoever form it may be embodied.

In the accompanying drawing,

Specification of Letters Patent.

Serial No. 335,361.

to show the manner of fastening the socket base to the brush.

Fig. 2 is an end View of the attaching base with the socket in vertical position.

Fig. 3 is a vertical section taken on the line III-III of Fig. 2.

In detail the construction illustrated in the drawing includes, the base or supporting member generally designated by the numeral 1 and comprising a bottom wall 2 with perpendicular side walls 3 and 1, formed integrally therewith on opposite edges. The side walls are preferably semicircular in shape, struck on a radius having its pivot point substantially in the center of each of the side walls 3 and 4. The edges of the side walls 8 and 4, are tapered as at 5 and 6 the purpose of which will hereinafter be explained in detail. Each of the side walls 3 aud t is drilled on the center point of the semi-circular radius and provided with the stub shaft 15 rotatably mounted therein, with the transverse hole 16 drilled and threaded therethrough.

For attaching the socket base to a brush or mop I provide the extensions 13 and 14 on the opposite ends of the base wall 2 tl'irough which screws, not shown, may be inserted into the back 1. The stud or projection 15 as shown on the drawing is formed integrally on the under side of the bottom wall 2 and provided either with spe' cial or standard threads adapted to screw into standard or special threaded socket provided in the back 1' of the brush. The handle socket 7 consists of a tubular extension 8 into which the wooden handle is adapted to be placed and securely held by means of the set screw 9. Adjacent one end of the tubular extension the socket is tapered to form the annular shoulder 10 and is further provided with the threaded stud 11. extending on from the shoulder 10.

in assembly the threaded hole 16 in the shaft 15 is held in position to admit the stud 11 being screwed therein until the annular tapered shoulder 10 frictionally engages the tapered portions 5 and 6 on the side walls 3 and 1, the purpose of which permits the'socket 7 to be frictionally adjusted to any position in the same plane, in an arc of substantially one hundred and eighty degrees, merely by rotatably adjusting the handle until it fixedly'engages in any desired position.

The annular shoulder 10 on the socket 7 also self-centers itself between the tapered shoulders of the side Walls 3 and I} thus providing a quick and easy means for adjusting the handle to any desired position.

I Having thus described my invention What I desire to claim and secure by Letters Patent is 1. A device of the character described comprising an attaching base having spaced side Walls; each of said Walls being semi-circular and having the edges thereof tapered; a shaft rotatably mounted in said Walls and a handle socket secured to said shaft adjustable radially thereof having a tapered shoulder thereon adapted to frictionally engage said semi-circular side Walls.

2. A device of the character described comprising an attaching base having spaced, parallel side Walls; each of said Walls being semi-circular and having the edges thereof tapered; a shaft extending between said side Walls and rotatably mounted therein and having a threaded depression; and a handle socket having a threaded engagement with said depression, provided With an annular tapered shoulder thereon adapted to frictionally engage said semi circular side Walls.

In testimony whereof I have hereunto set my hand at San Francisco, California, this 27th day of October, 1919.
